Windows Phone 7 Architecture Details Leaked

While we eagerly await the first Windows Phone 7 device, more details about its architecture got leaked. Tweakers.netgrabbed a leaked document that contained quite a lot of information about Microsoft's next generation mobile operating system. However, that information is tentative and may change when Windows Phone 7 handsets actually come out later this year.

The leaked document talks mostly about the technical internal working of the Windows Phone 7 architecture like two different file systems would be used. System files would be stored on IMGFS file system while user files stored on memory cards or internal flash storage will use TexFAT file system. Also, if the memory card containing some important files is removed, the phone would become mostly a paper weight.

Just like Apple has restricted the iPhone OS to iTunes and Google has confined Android only to other Google services, Microsoft will bind Windows Phone 7 to Windows Live ID. The Marketplace would be accessible and would be the only place to get apps by using Windows Live ID. Furthermore, the Windows Live ID would serve as the authentication key for data synchronization with Microsoft's servers.

Updates for the Windows Phone 7 devices would be distributed by Microsoft update system and would be downloadable via Over-The-Air or through the Zune software on PC.

Microsoft Tiles will exist despite the flexibility offered to mobile operators and manufacturers for adding custom tiles. Mobile service providers can also add up to 6 custom applications that would be pre-approved by Microsoft first.

One of the interesting details is the default search engine which usually would be Bing. However, service providers would be able to choose other search engine if they have exclusive deals one like AT&T has with Yahoo.
